hot module reload can't be repeated quickly

[LoganDark]

🐛 bug report

After hot-reloading a file, it takes 10-20 seconds before it can hot reload again.

🎛 Configuration (.babelrc, package.json, cli command)

much of it is confidential, so please let me know if you need something specific

🤔 Expected Behavior

If I save a file multiple times in quick succession, each time should trigger a hot reload immediately.

😯 Current Behavior

After saving a file, Parcel performs the hot reload and the changes show up in browser, but then Parcel for some reason decides to also rebuild like 15 other files that have nothing to do with what I just changed, preventing any more hot reloads from being applied until it's done.

💁 Possible Solution

1. Don't rebuild the bundle on hot reload until it's actually requested again.
2. Terminate the build in progress if another hot reload needs to happen before it's done.

🔦 Context

Rapid iteration is very difficult when I have to wait 20-30 seconds between each change. For context, in Vite, hammering stuff out with HMR and Tailwind is so fast. But in Parcel it takes forever.
